How durable is the Tripwire compared to other handles?
- The Tripwire is extremely durable and should have a service life as long or longer than the host firearm. It was specifically designed to address the issues of the standard / OEM charging handles. We have yet to hear of a customer that has worn out a latch since the product was released in 2014, and the current generation springs are rated to withstand 1,000,000 cycles. The #1 failure point for standard / OEM charging handles is located at the roll pin and latch junction due to excessive off-axis pulling force by the user and / or damage to the roll pin caused by shear forces transmitted from the latch itself. On the Tripwire, it is basically impossible for the user to cause catastrophic roll pin / latch failure because there is no extra force added to the junction when pulling the handle. Simply, the Tripwire's automatic locking system is isolated from user input. In case something ever did wear out, we would cover it under our unconditional, lifetime warranty.
Is this part designed for serious use?
- Yes, the Tripwire is designed for hard, daily use and is tested and reliable in nearly all weather conditions. The Tripwire is currently used by private military contractors, 3-gun competitors, law enforcement officers, security team members, and many firearms enthusiasts.
How does the Tripwire compare to Radian Raptor series of charging handles? Why should I try yours?
- The Tripwire 5.56-SCV is approximately 35 percent lighter than the Raptor SD and the Tripwire 5.56 is approximately 30 percent lighter than the standard Raptor. The Tripwire has a sleek shape that seems to blend in with most builds. There is no moving part except the automatic latch system, and the user doesn't have to manipulate that portion, so there's not much to fail or get snagged on. Usually, the Tripwire handles are available at a lower price. We like the Raptor and happily use it if needed, but the Tripwire was designed to be a lighter weight, less expensive, simpler alternative with a design that we like.
How are your charging handles made?
- The Tripwire is milled from a solid block of 7075-T6 aluminum and the current generation latch is cut from a UV-stable, engineering grade thermoplastic. Previously, the latch was 3D printed in carbon fiber, but we decided to move toward a new production process that allowed for higher volumes, improved durability and the ability to significantly slim down the profile of the latch, and increased dimensional accuracy. Our company name refers to an older style of 3D printing that we used for prototyping, and people sometimes confuse that with our manufacturing techniques.
How wide is the Tripwire and how does it compare to the standard handle?
- 2.54 in (Tripwire) vs 2.00 in (standard), or just about 1/4 inch wider on each side compared to the standard handle. We have never heard a customer say that the Tripwire is too wide. It was purposely designed so that the width does not exceed the brass deflector and forward assist. Here is a great picture of the standard handle placed over the Tripwire:
How heavy is the Tripwire and how does it compare to competitors?
- The Tripwire 5.56, 5.56-SCV, 7.62 are approximately 1 oz. Currently, all versions of the Tripwire are the lightest ambidextrous charging handles available in the market.
What does the Tripwire feel like to pull rearward?
- It feels very intuitive and extremely smooth. When pulling the handle back on a rifle with the BCG in the forward position, the unlocking force required is less than the action spring (buffer spring), so there is no perceptible extra pull weight. When pulling the handle back on a rifle with the BCG in the rearward / locked position, there is an initial pull required of approximately 10 lb, then the latch rotates and allows the handle to glide rearward.
Does the Tripwire's engineering grade thermoplastic latch affect the upper receiver?
- There should be little effect unless the upper receiver is painted. The latch material is softer and has a higher lubricity than any known material used on an upper receiver, and the latch geometry is also designed to minimize friction when both inserting and removing the handle from the locked / forward position. There should be significantly less wear on an upper receiver with the Tripwire's latch than with aluminum or steel latches found on all other charging handles. In fact, our testing has shown that a standard, hardcoat anodized upper receiver shows basically no wear with more than 20,000 cycles of the Tripwire. A painted upper receiver may show some loss of coating due to constant rubbing, but this is expected with any charging handle.
Did you copy the Mega Arms Slide Lock? What is the difference between the two handles?
- No, our provisional patent was submitted in April, 2014, and the Tripwire was released in July, 2014, several months before the Mega Arms product was announced. Our product is lighter and features a smaller profile, utilizes an engineering grade thermoplastic latch instead of their nitrided steel latch, and the latch geometry and spring rate are optimized in our product to eliminate wear to the upper receiver's latch locking point.
What is the point of the threaded hole and set screw on the rear-right of the Tripwire - SCV?
- Propellant gases can move along the bottom of the Tripwire, so that hole allows them to be expelled to the side before they exit into the shooter's face. Some shooters may prefer to plug that hole with the set screw if they are shooting entirely left handed or on an unsuppressed firearm. We prefer to leave the hole open at all times.
